` constructions without reducing the strength; also to provide animproved arrangementl of dimmer and improved means for holding lightobstructing guards at the sides.

For the purpose of making goggle frames out of sheet Celluloid so as toreduce the cost thereof to a minimum, according lto this invention thesheet of celluloid is irst stamped out by a single combined cutting outand stamping o eration to form the blank shown in Fig. This blank aswill be obvious consists of a single integral piece of sheet Celluloidhaving two circular or other Shaped eye-members 10 connected by a bridgepiece 11 and having projections 15 at its. opposite ends and alsosurrounded by a single integral continuous wall. 9 of sheet Celluloidabout the margin of the blank. This wall is at right angles to thesurface of the eye-pieces and other parts of the blank that are in thesame plane. It will be obvious that this blank can be formed 1n a verysimple, expeditious and inexpensive manner by the use of toolsof a typewellunderstood in this art.

The blank is stamped out by another cuttmg operation to remove thecenters from .the eye-pieces as shown more fully in Fig. l, and theseeye-pieces preferably are left with solid sheet Celluloid portions 12 atthe top formingv dimmers. This part of the construction is nished byplacing eye-pieces 10a in the circular or other shaped recesses orsockets formed as shown in Fig. 7 and having their edges cemented orotherwise secured to the flanges left around the edges of the eye-pieceswhen the centers are cut out. These eye-pieces can be of glass,celluloid, mica or any other desired material either transparent ortranslucent, and they can be of the general shape indicated in Fig. 1 orcan be circular so as to ll up the space back of the dimmer. 1f desireda sheet of opaque material 12a can be placed in the frame back of thedimmer to make its action still more eective. 1t will be understood, ofcourse, that ordinary sheet celluloid is somewhat translucent and theopaque material will materially enhance the value of the device as adimmer. I have also shown a strengthening rod 17 in the bridge of thegoggle cemented to both the plain.

wall thereof and the two curved walls.

These goggles are shownas provided with a pair of temples 13 formed ofCelluloid wire, or any other desired material, and in the presentinstance these are secured in' position by passing pins 14 through thehollow projections 15 at the ends of the frame. These hollow projectionsare formed like the rest of the frame of sheet celluloid and bytheoriginal stamping operation are left no separate operation required tomake this l seat for the temple hinge. As so far deotherwise have to beused only as waste.

It will be seen that each one of lthese guards is provided with twoparallel slits 21 and that the celluloid between the slits is bent up toform a cylindrical passage 'through which the wire temple can be passedand which is intended to it on it frictionally. Furthermore, each guardis provided with a notch 22 at the center of its straight surface Y forfitting the opposite sides of the projecwardly farther thanl would bethe casetion 15 when the guard is placed in position for use. Thisstraight edge of the guard also is preferably bent inwardly slightly sothat it has to be sprung over the end of the frame. Thus it will be heldin position after having once been sprung into place. This servesanother purpose also, because it prevents the temple being swungupwardly Ato the limit of its stroke and thus relieves the temple andthe end of the projection of the pressure they would get by suchaccidental motion thereof.

-The way in which the goggle is used will be obvious, also the utilityof the guards, and the dimmer. It remains only to state that when thegoggles are to be folded up the guards are pulled back on the temples soas to slide in out of the way to Apermit of folding the parts into smallcompass as indicated in Fig. 2.

In the form shown in Fig. 8, the above mentioned principles are allemployed eX- cept as to the guards. In this case each guard is formed ofapiece of celluloid 30 pivoted by pins 31 to the upper and lower edgesof the celluloid frame at diametrically opposite points and each guardis substantially semi-circular in shape and forms a part of acylindrical body. Being pivotedin this manner the guards can be movedinwardly to permit folding, as indicated at one side of this figure. Inthat case the notch 22 with which the guard is provided to enable it toslip over the projection' on the end of the frame' is availed of forreceiving the temple and permitting it to be folded inotherwise. Whenthe guards are in operative position they are held thereby the frictionof the material on the ends of the frame and need no other holdingmeans.

Although I have shown and described only two forms of the invention I amaware of the fact that modifications can be made therein by anyperson-skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore I do not wish to belimited to all the details of construction herein shown and described,but what I do claim is l. As an article of manufacture, a pair ofgoggles formed of sheet celluloid and consisting of a single integralpiece thereof, pressed and stamped out to provide a plain body portion,a longitudinal bridge and end portions, said body portion having two eyemembers spaced apart and having eye openings cut out of the same toleave a continuous plain rim therearound, the whole being provided witha single integral continuous marginal flangeat all points at rightangles to the plane of the said body portion.

2. As an article of manufacture, a pair of goggles comprising a plainflat member of, sheet celluloid having two eye pieces stamped out of thesame, said member being provided with flat rims around the eye piecesin. the plane of said body and having a bridge piece connecting saidrims integrally and in the plane thereof, said member having atransverse continuous marginal strengthening flange extendingtherearound, the bridge piece also having two marginal flanges integraland continuous with the first named flanges, two-hollow projectionsformed at opposite ends'of the Whole frame and'consisting of integralcontinuations of the' flanges of the flat member, and temples hingedwithin said projections.

3. As an article of manufacture, a pair of goggles comprising a plainfiat member of sheet celluloid having two eyev openings stamped out-ofthe same, said member being provided with flat rims around the eyeopenings in the plane of said -body and having a transverse continuousstrengthening flange extending therearound at the extreme outer edge,andeye pieces secured to thev rear of saidv fiat rims and free fromthemarginal flanges.

4. As an article of manufacture, a pair of goggles consisting of sheetcelluloid and having two eye-pieces integrally connected together andeach having a plain rim therearound provided with a portion at the topfor cutting off the light through the top part of the eye-piece.

5. As an` article of manufacture, a pair 'of goggles comprising a frameoflsheet celluloid having eye-pieces cut out therefrom and havingdimmers integral with the sheet celluloid at the top of said eye-piecesand provided with opaque members at the rear.
